For isolating carrageenan degrading bacteria, carrageenophytes, sediments and seawater collected from various localities along the coasts of Tamil Nadu were grown in mineral medium with carrageenan as sole carbon source. Bacterial isolates with carrageenolytic property were identified on the basis of their ability to form soft pits on the surface with clear haloes around its colonies, gradually turning the solid medium to liquid. Out of 38 isolates exhibiting carrageenolytic activity 3 each from marine sediments and decomposed algal samples and 13 from fresh seaweeds with strong carrageenolytic lesions were identified. Bacteria consortium Brevibacterium iodinumACa01 KJ754134 and Pseudomonas aeruginosaACa02 KJ754135 found effective for degrading carrageenan polymer as well as carrageenan biomass (Hypnea musciformis). Saccharification was more effective on spent biomass than on fresh biomass of Hypnea musciformis by mild acid pre-treatment followed by bacterial consortium than those biomasses directly subjected to bacterial consortium. In this study, Brevibacterium iodinumACa01 KJ754134 and Pseudomonas aeruginosaACa02 KJ754135 as consortium capable of degrading carrageenan rich seaweed biomass reported for the first time.
